, will present an odd number of bricks on'one row with lan even number disposed on top of A,the odd number of bricks.l

Another object of the inventionis the provisionof a mold having hinged doors oflstep formation and afa'ce plate cooperating with the doors and a .plurality of cores 'movable through a back plate.

Awfurther object of .the invention lis'fthfe provision yof a mold for forming a concrete blockk of a particular formation and in which end doors are hinged to afframe which is swingable toa vertical positionforcooperation with ya horizontally disposed face plate. a core adapted to be moved in a horizontal planeinto the moldl and guided by a back plate through which'the cores are inserted. This invention `will be best understood from a consideration of the following detailed description in view of the accompanyf ing drawingsf'lforminga partof the specification; nevertheless it is 'to be understood that the invention is not confined to thedisclosure, being susceptible of such changes and modilications which shall-define no material departure vfrom the salient features of. the in-v vention as expressed in theappended claim. v In the drawings Figure 1 is a view in perspective of a mold-- ing machine constructed inaoco'rdanceiwithv the principles of our 'inventiom Y Figure '2 is an end'l "ewshowing the mold in open 'positionwith the concrete bloclrreversed" Figure 351s aview in perspecti've offa crete block which is formed by'my molding machine, p'

A plate 14 is secured to the frontlegs 13 Vand has a 'horizontally disposed flange 15 carrying adjustingl bolts v16 threaded into perforations in. said tlange.-vr l `A pair vof arms 17 are pivotally mounted at 18 on the table and are provided with horizontal extension19.

The arms 17` are adapted bolts/1b.]V t

A pair `of push-rods 21 are slidably mounted in the passage v22 in the extensions 19 Aand a spring 23 embracing a rod 21' en'- tol rest .uponthe upper ends ofthe adjustable gages the head 24. offsaid rod andialso thev outer face orI the yface plate 20, said rod passing through. aperforation in the plate at the lower end thereof. t The inner end of. each rod21 isexpanded as shownat 25 and seated within a similarly shaped socket 26 at ythe inner surface of the face plate to prevent said pushfrod from being accidentall discharged fromtheface plate. A pair o bolts 27 secure theface plate to thek extensions'19 and also `prov'idemeans for adjusting'the. face plate relative to t-he extensions 19.

The push rods are operated by an actuating lever 28 secured to a rod 2 9- which is rotatably mounted vin the side bars 1l `and 12. 'Ahaudle 30 providesfmeans for actuating said lever for forcingthe said lever into engagef mentwithl the head 24 yofthe push rodto slide .I i

a pallet 31horizontallylalong the arms 17kl and laway from the face-plate '20fa'fterthe block has been completed. .It will be noted thatvthe levers 28 aremounted in spaced rela- 'tion'ontherod 29 so that when oneof the levers is actuated the other lever will belop-L Y:

erated simultaneouslyso that both levers act upon theV push rods 21 to provide a uniform horizontal movement of the pallet 31.

The inner surface ofthe face plate isiproi i vided with a rib35 and pockets 36 with intersecting or transverse ribs 37 and y38 to pro" vide for the appearance of the brickvk formation on the face of vthe blockwhensaid block pockets 36. .These ribs provide for the de,

pressionsf41 and 42 ofthe outer face of the has' been completed. The periphery of the lock while the curved edges' of the pockets'v l cause a slight bevelling as shown at 4l?) and 114;, of the block L15 so that when the blocks are fitted together in a building1 the wall of the building` will give the appearance of having been built of bricks.

is. pair of doors generally designated by the numerals Ll-b and 47 are hinged at 18 0n a pintle 49 carried by extensions of the arms 17. Each door consists of a pair of vertical plates 50 and 51 connected together by a horizontal plate 52 to provide a step formation and in which the plate 52 approximately half 'the width of a brick section 53of the block rlie plate 50 is cut away at 5a and adjacent the hinge 18 to neatly receive an end of the pallet 3l. Each of the doors has pivotally connected to they outer face of the plate 51, a catch 55 which engages overI an edge of a buel plate 56 for lockingthe back plate to the'doors 46 and 4-7.

lheback plate 56 is provided witha plurality of passages 57 through which are adapted to be moved a plurality of hollow cores 58. rl`he back plate is reinforced by cleats 59 and strapstO'are securedto said bars and hinged at 61 to the side bars l1 and 1Q ofthe table. 'lhe back plate may be swung' away from the bloei-k and likewise the mold when said block is set.

v'lbe'cores 58are connected together for simultaneous movein'ent'and a lJ-shaped reH ciprocating rod 7 O is secured to one of the cores and adapted 'to be oscillated in guides onbrackets 71 `secured to the side bars 11 and 12, A link 7 2 is pivotally connected with the reciprocating rod 70 and witha yoke 73 hingedly Connected at 711 to the side bars 11 and 12. An operating handle 75 is rigid with the yoke so that when vthe same is oscillated the rod 7 0 will be reciproeated in a horiZon-. tal plane for movingthe cores 58 in the saine horizontal plane. y

il. mold 8() is mounted on the opposite end of the tablelU for the purpose "of producing a block which is rectangular in cross section .and whichhas one face formed'to simulate a plurality of bricks cemented together.

The operation of our device is as-follows The mold. section is swung to the' position shown in lligz7 with the face plate 2O supported by the side bars 11 and 12 of the table and the arms 17 disposed in ai vertical position with the pallet 31 likewise'loeated in vertical position and in engagement with the arms 17. The' back plate is swung on its pivot and has itslower edge seated upon the inner face adjacent the inner end of the face plate. The handle 75 is actuated causing therod 70 to be movedvinwardlyin a` horizontal plane and positioning the cores 58 abovethefaceplate and with the ends of the cores in engagement with. the pallet 31. The Adoors d6 and 47 are'then moved to the proper position' and the VConcrete is filled into the mold and around the cores 58 and sufficiently tamped to prevent air pockets. rlhe latehes 55 are moved into position so that they will engageV over the vertically disposed ends of the Vback plate `56. Since the mold has been retthe handle 75 is moved outwardly until therpin 81 engages'thejguide 71 and limits the outer movement of the' cores 58. The back plate 56is then' moved away from the mold `andthe arms'17 and swung to the horizontal position where they will'restupon 'the bolts 16. Either one of the levers 28 is rocked forcing the pushV bolts linwardly and'moving the pallet Slaway from the face pla-te so that the lock may be readily'reL 1noved`,'after the latches' 55 have'been'released frointhe back plate 56;v

he doors 116' and 47 and the back plate 56 close on top of a face plate 20g sot-hat the lower Vedge of the door .is aligned' with the rib 39 and over 'thecontinuation ofthe rib` with oneedgeofthe face plate;` The'back plate 56 is also aligned over 'the' top Vofi this rib'and the edge 'of the palletj31 'on' which the block rests also jrestson' the edge of v'this' plate so that the doors, back plate and pallet are all in alignment with the inside edge' of the rib 89which is disposed around the entire outer edge of the face plate.

VJs claim A mold comprising a face plate, arms projecting laterally from the face plate, a pallet supported upon said' face plate, doors hingedly mountedon the armsya back plate and a core Carried by the back platefadapted to lbe positioned o ver the faceplate, push rods slidably mounted in the face plate andV adapted toengage'an edge of the' pallet7 'and means for reciprocatingV the'pusli rods for forcing the pallet away from the faceplate.
